calculate output $y(t)$ from $Y(z)$ having discrete closed loop model with sine input - residue method
I have closed loop - discrete model. This is how it looks in matlab:
I need to compute analitically output $y(t)$ (same as in the Matlab's scope) having $Y(z)$.
Where
$Y(z)=U(z)*G(z)$
Input is sine ...

Question on sketching nyquist plot of transfer function with poles on imaginary axis
I have encountered some issues with sketching the nyquist plot for the following loop transfer function:
$L(s) = \frac{25K}{S^2+25}$
I know that you first take:
$L(\omega=0) = K$
$L(\omega = ...
